Our mission

Make real offensive security continuous and accessible.

Most organizations get one penetration test a year and a report that's stale by the time it lands. Arsenal changes that. We run continuous, operator-led assessments against your real environment, delivered as a managed service or as a platform your team can run themselves, so you see what an attacker would see, every month, without your data ever leaving your control.

About

Why we built it.

Every engagement used the same stack of tools. Each one was okay at its job. None of them talked to each other. Credentials harvested in one phase never made it into the next. Attack paths surfaced by one tool never connected to the modules that could exploit them. More time went into rebuilding context between tools than into the work that actually mattered.

The commercial platforms that promised to fix this fell short. Most were cloud-managed, meaning sensitive data had to leave the customer's network to be processed somewhere else — a non-starter in ICS/OT and an uncomfortable conversation anywhere else. The rest aggregated dashboards instead of connecting intelligence.

This wasn't a hypothetical frustration. It came from over a decade of offensive security work, running CNE operations for U.S. Cyber Command and the NSA out of Tailored Access Operations, then leading industrial penetration tests across electric utilities, water, oil and gas, and other critical infrastructure at a leading ICS/OT cybersecurity firm. Those engagements made it clear exactly what was missing. That deep experience in the field is also what produced this book on industrial network pentesting, Hacking OT Networks: A Practical Guide to Pentesting Industrial Networks.

So our founder built the platform he wanted to use.

A full AI-powered offensive security platform with every capability an operator needs, unified into one system. Every finding sharpens the next. AI reasoning grounded in the environment without sensitive customer data ever leaving the appliance. Built for both IT and ICS/OT.

The name reflects what it is. An arsenal — every weapon in one place, working together as one system instead of a pile of disconnected tools.
